Hello all

 

I am trying to model a count outcome (emergency room visits) with a primary predictor covariate of interest that is time varying (on or off a drug). Once the drug is started, they patient is considered "on" the drug going forward (ie they do not revert to being off the drug).

 

My data is structured in a counting process (multiple lines per individual) for each risk interval. 

 

Does anyone have any resources as to where I would find code to do this? Can proc genmod handle a counting process data structure?

I am not really sure where to start...

It seems you have longtitude data.

Try PROC GLIMMIX or PROC GEE

Thanks

 

It seems those procedures are more suited to my data.
